O Lord God almighty, I supplicate Thee, through the precious body and blood of Thy divine Son Jesus, which He Himself on the eve of His Passion gave erewhile for meat and drink to His dear apostles, and left to all His Church as a perpetual sacrifice and lifegiving food for His faithful; set free the souls in purgatory, and most of all the one most devout to this mystery of infinite love; in order that it may praise Thee for it with Thy divine Son, and with the Holy Ghost in Thy glory forever. Amen.
